\WMALFXGFXDSP.dll).Ĭan it be some other USB driver is interfering with this driver stack? I have no idea how to figure out which one it could be. \USBAUDIO.sys and \windows\system32\SysFx.dll. On the other system I find ksthunk.sys in addition to the modules that are listed on my system as well (beeing \windows\system32\drivers\drmk.sys. On that other system the device works like a charm (so it is not the hardware, either).

I compared the driver details from my system (Dell T1500 windows 7 pro 64 bit) with those of another windows 7 pro 64 bit. The same thing occurs with a USB-MIDI-Cable. The problem is not related to MIDI output! I have it with a pure USB-MIDI-input device (keyboard), whichs produces "unknown externeal error" every time I try to select it as input. I am so glad I found keyman7's description, since I have exactly the same problem. I'm an IT professional (network and systems admin), so you can be fairly technicalĪny suggestions will be welcome.
I've been struggling with the MIDI problem for most of that time.

This is a Dell XPS 8300 Windows 7 64-bit PC with all the latest updates, only about six weeks old. I've followed those threads, and done several of the suggestions, but haven't found a solution to this one. The Microsoft forums contain a fair number of users reporting similar problems, some are audio and some are webcam So it looks like it may be a Windows 7 config problem on my machine, and I'm hoping someone here can give me some advice on how to fix it. On this machine, that driver just doesn’t hook up to the Yamaha MIDI driver and show up in the stack. So far, no amount of re-installation, event viewing, uninstalling devices, numerous reboots,etc has fixed it. I was also advised by Yamaha to edit registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32 and remove all midi, midi1, midi2, etc entries, then uninstall and reinstall all drivers. I have also tried three different USBĬables (but those shouldn't be an issue since the keyboard is showing up in Windows). Yamaha MIDI Driver is shown in Control Panel/Sound, and it can be worked with there (opened, closed, configured, etc.). ksthunk.sys is on my machine in c:\windows\system32\drivers\Īnd in the registry the image path is \SystemRoot\system32\drivers\ksthunk.sysĪll devices are “working properly” in Windows Device Manager, despite that missing driver. They have never heard of this driver not showing up there, and they cannot reproduce the problem. Sounds like that would relate to MIDI data. Is ksthunk.sys, which I think handles kernel streaming. (You can see this in Device Manager, Properties/Driver tab, then Driver Details. Yamaha tells me that their USB-MIDI driver is installing fine on my machine, except that it’s missing a windows driver at the bottom of the driver stack. And I cannot sync to the keyboard due to the above error message. In my case though, everything shows up in Windows, but MIDI doesn’t actually They assure me that those work for other users of Win7 64-bit. And the latest versions of all their editing software for Win7 64-bit. I am using the Yamaha USB-MIDI driver versionģ.1.2 for Windows 7 64-bit (the latest driver). I have a Yamaha SX70 XS keyboard, which is recognized by Windows as a connected USB device. I have been working directly with Yamaha tech support on the issue for some time. At first, MIDI was working and I could sync up, but after about a week, right around the time I uninstalled and re-installed a MS Lifecam, it failed and has not worked since. “The following MIDI ports can not be opened at this time”. The error message in the Yamaha software reads The problem is that even though my devices are recognized in Control Panel/ Sound and in Device Manager, no MIDI data actually flows and I cannot sync my keyboard to the Yamaha software that edits it.
